No. 729,485 Int. Cl. E21c 9/00, 11/00 US. Cl. 173-43 12 Claims ABSTRACT OF THE DISCLOSURE Pile hammer leads are adjusted side-to-side to full batter angles of inclination, being pivoted to a carriage which rides over a short straight beam pivoted in line with the bottom brace of the rig and which is extensible from this pivotal mounting to reach the leads out to the desired angles of inclination and retractable to reduce the sidewise projection, for operation in a restricted area.

The general objects of this invention have been to provide practical and effective equipment for operating a pile hammer in areas limited in operating space, such as, for instance, would prevent the use of conventional pile driving equipment having the long curved moon beam form of batter adjustment.

Other desirable objects attained by the invention and the novel features of construction, combination and arrangement of parts embodying the invention are set forth and will appear in the course of the following specification.

The drawings accompanying and forming part of the specification are illustrative of a preferred embodiment of the invention, but as will appear, the structure may be modified and changed as regards the present illustration; all within the true intent and scope of the invention as hereinafter described and claimed.

FIG. 1 is a front elevation of one of the new universal batter adjustments with broken lines indicating reverse sidewise adjustment of the batter angle.

FIG. 2 is a side view of the machine.

FIG. 3 is an enlarged broken sectional view on substantially the plane of line 3-3 of FIG. 2.

FIG. 4 is a broken plan view on substantially the plane of line 4-4 of FIG. 2.

FIG. 5 is a perspective view of the carriage to which the lower end of the lead is pivoted.

FIG. 6 is a perspective view of the head which carries the beam for the carriage.

FIG. 7 is a broken sectional view across the beam showing the pivoted supporting head at one side and the carriage for the leads at the opposite side.

FIG. 8 is a sectional detail of the stop pin for locking the beam in different adjusted positions in the supporting head.

FIG. 2 shows a lead 10 for a pile hammer, pivoted at the top at 11 on the point of a beam 12 for fore and aft batter under control of the bottom brace 13, which may be of the powered type shown in Patent No. 3,344,- 867 of Oct. 3, 1967.

FIG. 1 shows the lead pivoted at 14 in a fore and aft direction for side batter.

The lower end of the lead is pivoted at 15 to a car-riage 16 which rides over a short straight beam 17, which is longitudinally shiftable in a head 18, rotatably mounted on an axis 19 in line with the bottom brace.

The beam 17 is shown as an H beam, disposed with the web 20 of the same horizontal, thus to locate the inner pair of flanges 21 between upper and lower rollers 22, 23 and front and back rollers 24, 25, on the rotatable sup- 3,463,245 Patented Aug. 26, 1969 porting head 18 and flanges 26 at the front engaged by top and bottom rollers 27, 28 and back rollers 29 on the travelling carriage 16.

FIGS. 6 and 7 show the rotatable supporting head 18 as carried by a spindle 19, mounted to turn on the end of the bottom brace 13.

A bridle 30 for supporting and steadying the ends of the beam is shown in FIG. 1 as run up over a guide sheave 31 on the center 14 on the point of the beam.

To spot the beam in centered position on its angularly adjustable support and in definite extended and retracted positions, lock pins 32, FIGS. 3, 4 and 8, are provided which can be inserted into openings 33 in the beam, at opposite sides of the supporting head 18.

The beam may be shifted manually or by power and may be locked in the centered or off-center positions by the locking pin or pins 32 described.

The side batter adjustment of the leads is effected in the illustration by drag lines 35, 36, FIGS. 3 and 4, adjustably connected at 37, 38, with opposite sides of the travelling carriage and run over sheaves 39, 40 on opposite ends of the beam and over lower and upper guide pulleys 41, 42, 43 and 44, down to a reversible motor driven drum 45, FIG. 2 in the cab of the crane.

With the stop pins in place at opposite sides of the supporting head, the beam will be held against longitudinal movement in the head and the pull on the lines 35, 36 will have the effect of shifting the lead positioning carriage along the anchored beam.

On removal of the lock pins, the beam will be freed for longitudinal adjustment in the head and the powered shifting lines 35, 36 may then be used to shift the beam outward and inward in respect to the supporting head.

The cables may thus be used for the double purpose of longitudinally adjusting the beam to any desired extent or shifting the batter setting carriage on the beam.

The beam may be relatively short as compared to the ordinary moonbeam, but may for instance be full 20 feet so as to reach, when extended, as far or further than a moonbeam.

This 20 foot beam may be retracted to or past the center of support to fully avoid interfering structure that would prevent operation of a moonbeam in such a location.

In operating the system, the support head is left free to turn on its axis so that with pull on line 35 or 36 the carriage will apply pressure to rock the beam one way or the other as necessary to keep the beam lined up for straight travel of the carriage along the beam.

What is claimed is:

1. Pile hammer batter adjustment means comprising the combination with a crane having a boom and a pile hammer lead pivotally suspended from the point of the boom for fore and aft and side batter, of

a pivotally mounted angularly adjustable supporting head, beneath the lead,

a beam longitudinally adjustable on said supporting head transversely of the axis of said angular adjustment of the supporting head,

a side batter adjusting carriage longitudinally shiftable on said beam and pivotally connetced with the lower end of said lead on. an axis parallel with the fore and aft pivotal axis of the lead, and

means for effecting shifting of the carriage on the beam to different angles of side batter or centering of the lead to vertical drive position.

2. The invention according to claim 1 in which said beam is a length of H beam having flanges at opposite sides connected by a web and in which said beam is disposed with said web in horizontal position and the flanges vertical, with the flanges at one side engaged in said supporting head and the flanges at the opposite side engaged by said carriage.

3. The invention according to claim 1 with readily releasable means for locating and holding said beam in different adjusted positions on said supporting head.

4. The invention according to claim 3 in which said means includes stop pins at opposite sides of the supporting head engageable in selected openings in the beam.
